Description
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to application allows the renewal of nearly-expired token leases and dynamic secret leases (specifically, those within 1 second of their maximum TTL), which caused them to be incorrectly treated as non-expiring during subsequent use. A remote non-authenticated attacker can obtain or guess session token and gain unauthorized access to session that belongs to another user.
